How many of you are running the new DA150L?
- Thread starter Super08
- Start date
WOW, is all i can say. big difference.
yesterday, with the
TBM wood prop 32 x 10, max RPM was 4600
today, with the Falcon CF 30 x 13 W, top RPM was 5600.
huge increase, and the pull was just amazing. i felt it way much more this time compared to yesterday. with what it has now, i feel this airplane can take off no problem,. yesterday, i had my doubts as it felt weak. It is alive now!!! the spool up was faster than yesterday, but still sluggish.
i can only imagine spool up will be better and top RPM will be higher with the Mejzlik 30 x 12 L
this is with DA 150L
10.25" headers
Large pro flow canisters
using this:

i get this:
TBM 32 x 10 wood prop @ 4600 rpm = 41 lbs static thrust
Falcon CF 30 x 13 W @ 5600 rpm = 66 pounds static thrust
if
the Mejzlik CF 30 x 12 L gets 6000 rpm, then static thrust would be = 71 pounds static thrust
i do not know how accurate this calculator is, but at least it will give me a rough idea on the change in thrust by changing the props!!
anyone think this motor can reach 6000 rpm with the 30 x 12 L CF prop????

IMAC FANATIC
40% happier than most folks.
More rpm's means more prop noise though doesn't it ? Wont matter of its not used for IMAC though, did you get db ratings when tested ? Just wondering.
